The fish is officially a danio now, Danio erythromicron, and known to be a very close relative of CPD. One of my favorites, I keep two tanks of them they should not do too much damage to shrimps, but I'm not sure if Java Fern is enough for them to feel safe, my tanks are half-filled with Najas... the more plants, the better.

And if there is enough plant cover and you feed them well, some fry may survive.... I get natural fry if the number of adults in the tank is around 5, with 10+ this never happens.

They just struck me as being so cool looking, and I like small fish sometimes.

Did a massive water change - 80% - before introducing them so the tank could also act as a quarantine tank. My fish all seem to be doing well, so I have been in a kind of "no new fish - no new dangers" mode, lol.

They were $4.99ea and they gave me 5 for $20. Even better, I had $120 in store credit available. And I got a couple without strong banding figuring those might be females. 5 should be sufficient for a 10g, right?

In regards to the plants, this is the tank. The photo was taken in Nov and I haven't really trimmed since then. All the stems are growing out of the sponge filter, lol. They seem content swimming around in the jungle.

They seem to hover a lot like a hummingbird looking for food. Just cool little fish I never knew existed before.

They are one of my favorite nano fish. the colors they can produce when happy are amazing. My only gripe is that they tend to be very skittish and hide when they can. As it sits now I have a fluval flora with a few of them that are about 3-4 years old and a bunch of ruby tetras.
